Mirage Express is a decommissioned cargo train that worked with the Conductor for over thirty-two years. Recently, it was modified into a passenger train-like Badnik by Dr. Eggman to transport civilians away from their hometowns. During Amy Rose's birthday, amid fears of being abandoned by the Conductor, the Mirage Express selfishly served the doctor under the promise that it would reunite with its friend but met its demise at the hands of Sonic and his friends.
